You cannot judge by outward appearances; the soul is only
transparent to its Maker.
- Hosea Ballou

His heart is as firm as a stone; yea, as hard as a piece of the
nether millstone.
- Bible, Job (ch. XLI, v. 24)

Ye are the salt of the earth: but if the salt have lost his
savour, wherewith shall it be salted? it is thenceforth good for
nothing, but to be cast out, and to be trodden under foot of men.
- Bible, Matthew (ch. V, v. 13)

It is the qualities of the heart, not those of the face, that
should attract us in women, because the former are durable, the
latter transitory. So lovable women, like roses, retain their
sweetness long after they have lost their beauty.
- Alphonse de Lamartine
